    Dual. Climate control. No cooling after prolonged stop. 5-6 minutes pass after restart and drive then works but not extremely cold 50 degree vent temps. System charge good. Any thoughts?

    Hi your car probably has a pump with variable output ,you have to check this with
    airco tester to check the suction and pressure side of the pump.

    Hi, you do not have to test the fuel rail pressure, you need to check the airco suction
    and pressure in the airco system by a airco specialist,i do not know if you can do this
    yourself.
